Not necessarily. Depends on a few factors, such as how many additional apps (on average) the typical PG guest will have. Trust me, the bean counters at HAL have these numbers.
My personal experience prior to adding the surcharge was that I have seen various guests on different occasions order multiple apps along with their main, sides and desserts.
And the surcharge doesn't apply to the more and more folks that are receiving a 'free' PG dinner as part of their HIA, or any other promo they may have.
